 > I've identified all (hopefully) the callers in the parent firefox and
 the child plugin_container (nothing unique in plugin_container though that
 isn't called in the parent).  The spawned glxtest also has lots of reads
 going to /proc as well.

 I don't know but you could mess with Yawning's `sandboxed-tor-browser`
 (which brought this issue up in the first place), see: #20773 and the
 patch for it in 95857360ec7f84cf9f0a01855c15881c89919133.
